Leveling device for planar objects

Abstract

A leveling device for planar objects includes a first part having a circular end hole, a chamber, a flange, a handle, a contact portion, two blades and a bottom face. A second part includes a receiving hole, a first shoulder, two recesses, a slot, a mark, an axial hole and a second shoulder. The first and second parts are connected to each other. A movable member movably inserted into the first and second parts. The movable member includes a push potion, a middle section, a lower section and a room. An engaging member is securely inserted into the room and has a lower portion extending beyond the movable member. The engaging member is movable with the movable member. A resilient member is mounted to the lower section and biased between the middle section and the second shoulder.

What is claimed is: 
     
       1. A leveling device for planar objects, the planar objects being fixed to a flat surface, and the leveling device comprising:
 a first part having a circular end hole defined in a top thereof, a chamber defined through the top and a bottom of the first part, the chamber communicating with the end hole and having a flange extending inward from an inner periphery thereof, two hooks extending from a bottom face of the first part; 
 a second part having a circular receiving hole defined in a top thereof, a lower portion of the first part received in the receiving hole, a first shoulder extending from an inner periphery of the receiving hole, the bottom face of the first part rested on the first shoulder, two recesses defined in the inner periphery of the receiving hole and the two hooks being hooked with the recesses so that the first and second parts are connected to each other, the second part having a slot defined radially therein, and an axial hole defined axially therein, the slot communicating with the chamber and the recesses, a mark formed on an outside of the second part, the axial hole communicating with the end hole, the slot located between the receiving hole and the axial hole, a second shoulder formed between the slot and the axial hole; 
 a movable member having a push potion on an upper portion thereof and a lower section on a lower portion thereof, a middle section extending from the movable member and located between the push portion and the lower section, the push portion movably extending through the chamber and protruding beyond the top of the first part via the end hole, a shape of the middle section being shaped to be movable in the chamber of the first part, a room defined in a lower end of the lower section; 
 an engaging member securely inserted into the room and having a lower portion extending beyond the lower end of the movable member, the lower portion located in the second part, two blades extending perpendicularly from the lower portion of the engaging member, the two blades exposed beyond the lower portion of the engaging member and extending along a direction identical to a direction that the mark extends, the engaging member having an upper portion which is fixed in the room, and 
 a resilient member mounted to the lower section and biased between the middle section of the movable member and the second shoulder of the second part, the middle portion contacting an underside of the flange by the resilient member. 
 
     
     
       2. The leveling device for planar objects as claimed in  claim 1 , wherein the chamber is a hexagonal or polygonal chamber, the slot is a hexagonal slot, the middle section is a hexagonal section. 
     
     
       3. The leveling device for planar objects as claimed in  claim 1 , wherein the first part includes a handle and a contact portion respectively and diametrically formed on outside thereof, the handle and the contact portion are located on a straight line that extends along the direction of the mark. 
     
     
       4. The leveling device for planar objects as claimed in  claim 3 , wherein the handle and the contact portion are formed as a circular disk. 
     
     
       5. The leveling device for planar objects as claimed in  claim 3 , wherein a gap is formed between two adjacent planar objects, the contact portion and the mark are located corresponding to the gap, the blades are located corresponding to the gap, when the push portion is pushed downward, the middle section is lowered to compress the resilient member, the movable member and the engaging member are moved downward, the engaging member extends through the gap, when the engaging member is rotated 90 degrees, the blades are rotated and located at two respective undersides of the two planar objects, the mark is removed from the gap and points the planar object, the blades are perpendicular to the gap, when the push portion is released, the resilient member pushes the movable member and the engaging member upward, the blades contact the undersides of the two planar objects. 
     
     
       6. The leveling device for planar objects as claimed in  claim 1 , wherein the chamber includes a V-shaped groove defined therein, the middle section has a protrusion extending therefrom, the protrusion is movably engaged with the V-shaped groove. 
     
     
       7. The leveling device for planar objects as claimed in  claim 1 , wherein the mark is shaped as an arrow head. 
     
     
       8. The leveling device for planar objects as claimed in  claim 1 , wherein the second part includes multiple ribs located therein. 
     
     
       9. The leveling device for planar objects as claimed in  claim 1 , wherein the engaging member is integrally formed with the movable member. 
     
     
       10. The leveling device for planar objects as claimed in  claim 1 , wherein the first and second parts are an integrally formed as one piece, the axial hole and the second shoulder are formed as a first member which includes outer threads, the axial hole is defined through a center of the first member, the second shoulder is located on a top of the first member, the slot includes inner threads to which the outer threads of the first member is connected. 
     
     
       11. The leveling device for planar objects as claimed in  claim 1 , wherein the movable member and the engaging member are formed as one piece. 
     
     
       12. The leveling device for planar objects as claimed in  claim 1 , wherein the first and second parts are an integrally formed as one piece, the end hole and the flange are formed as a second member, the end hole is defined through the second member, the flange is located at an underside of the second member, the first part includes inner threads in an open top thereof, the second member is connected to the inner threads to be connected to the first part, the end hole communicates with the chamber.
